Could the breakup possibly have been a catalyst for his incredible summer? Yes, according to McIlroy.

"I think what happened has been for the better in terms of my golf. I've put a bit more time into it and it has refocused me. I mean, what else do I have to do now? I go to the golf course, I go to the gym and it's just my life at the minute," McIlroy told ESPN before the final round of the PGA Championship. "I worked pretty hard before but the past couple of months I've really just buried myself in my game. It obviously works pretty well, so I am going to keep doing it."

McIlroy and Wozniack had been dating since 2011 and were engaged this past New Year's Eve. During the 2013 season leading up to his engagement, McIlroy didn't record a win on the PGA Tour, even missing the cut at the British Open. In the middle of his bad season, NBC analyst Johnny Miller speculated that his relationship was throwing him off.
